19 Claims. '(01. 292 -272) This invention relates to holding means forclosure members having a hinged or relatively pivoted support, and itsprincipal object is to provide a holding means that will effectivelysecure a closure member in any one of several predetermined states ofopening.

Door guard devices as they are known to applicant have the common faultof being loosely coupled members that permit movement of the door to andfrom the casing in a breeze or draft of air, which produces muchrattling and slamming and is therefore a constant annoyance to a roomoccupant and others within hearing. When the door closes due to a gustof air, the guard 5 device fails to serve the function for which it wasintended, that is, to hold the door open to provide ventilation. Onesuch device is that commonly known as the chain door guard. It is aguard only, and is not a door stay, since it will not hold 20 the doorin part open position against unintentional forces applied to the door.

It is therefore another object of the invention to provide a door stayfor closures in dwellings and the like that will effectively hold a doorin a selected open condition against'drafts or air currents, and thatwill be secure against disassociation from the outside.

Another object of the invention is to provide a relatively rigid doorstay; that maybe adjusted from one side of the door either to firmlyhold the door in any one of several positions of opening or to retainthe door in securely locked condition,but which will not be accessiblefrom the other side of the door in either instance for disassociationwhen it is indoor holding adjustment.

Another object of the invention is to provide a holding means forahinged door, that will effectively retain a door in any one of aninfinite 40 number of open positions within the. limits defined by theholding means.

Another object of the invention is to provide a door stay with frictionmeans for holding a door in a selected part open-condition againstaccidental or unintentional closing forces, but which will not preventclosing of the door by intended forces.

A further object of the invention is to provide a door stay incooperation with a door handle as original equipment in architecturalinstallations, whereby the hardware fittings thereof may be reduced to aminimum, and yet effect partial opening of the door though securedagainst unauthorized entrance therethrough.

A further object of the invention is to provide a fixture for a closuremember, adaptable for diversified installation, whereby it may serveeffectively either as a friction stay for an infinite number of openpositions, or as a stay and opening guard proof against disassociationfrom the 5*;

opposite side of the closure.

Another object of the invention is to provide stay means for pivotedclosure. members; thatwill automatically adjust itself in response toeither an opening or closing thrust to retain the 10-1:

closure member in the exact open position to which it has been moved. Afurther object of the invention is to provide a door stay thatwill-effectively operate to hold a closure member in any selectedposition from tightly closed up to wide open at substantially and yetmay be quickly uncoupled to permit free swinging'of the closure member.

A still further object of the invention is to provide a door handle thatwill operate as a12 keeper for a door guard, by which the door ispermitted to open a limited amount.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings wherein a preferredembodiment of the present invention isclearly shown.

In the drawings: Fig. 1 is a front elevational view of a guard devicemounted on a door and casing and coupled in guarding and stayingrelation.

Fig. 4 is a similar view, but shows the guard device in a shiftedposition incident to that taken when the door is in part open position.

Fig. 5 is a vertical sectional view through part of the mechanismsubstantially as indicated by the line and arrows 5--5 of Fig. 1. 4

Fig. 10 is a View similar to Fig. 9, but with the parts moved to aposition for coupling the handle and stay means.

Fig. 11 is a transverse sectional view through the handle, substantiallyas indicated by the line and arrows H-li of Fig. 9.

The foregoing objects are accomplished and the stated fault is overcomeby providing a swiveled boom member with a lateral arm cooperating witha guide, and retainable in a selected posi- 1 In the preferred form,-

, turning. That assures that the slots 30 and 38 tion by a frictiondevice. the boom is mounted firmly on the casing with the associatedfriction device housed within the casing. The cooperating guide iscombinedwith the well known door handle and affords a slot in the bodythereof for reception of one end of the lateral arm, when the latter isrotated to extend across the gap or seam between the closure member andeasing therefor; there being means for either securely coupling oruncoupling the lateral arm and slotted member as occasion demands.Whenmounted adjacent the free edge of a pivoted closure member, such asa house door, the device operates as a door guard and friction stay forholding the closure member in an adjusted open position, and preventsopening beyond a predetermined limit by an unauthorized person. Whenmounted adjacent the pivot of the closure member, whether the member bepivoted at one edge or at some intermediate point between the edges, thedevice operates as a friction stay for holding the closure member in anyselected open position from closed up to about In any instance ofmounting, the boom and guide elements are quickly and easily coupled andun coupled from a point on one side of the closure member, but areinaccessible of either manipulation from a point on the opposite side ofthe closure member. I

With more specific reference, and particularly to the drawings, I0refers to a door or closure member of the hinged or pivoted type, beingsupported by or surrounded by a frame or casing l2. The hinges or pivotsfor the door being conventional structure are not shown. Along the meeting or free edge of the door, adjacent the gap l4 between it and thecasing, a handle I8 is mounted by screws 20 extending through apertures.22 in feet 24 and 25, one attached at each end of and supporting thehandle I8. The handle is of particular construction, and differs fromthe known prior art, in that the hand engaging part or bar 28 is hollow01' tubular, and is provided with a' pair of longitudinal slots 30, eachopening at one end into a transverse slot 32. The slots 30 with theconnecting slot 32 are so arranged in the tubular bar thatthe cross slot32 opens in the face of the bar, while the slots 30 extend from the endsof the slot 30 along the sides of the bar. That construction provides onthe front face of the bar an overhanging tongue 34.

Loosely fitting within the bar 28, there is a plunger 36, that in turnmay be hollow or tubu lar, or on the other hand it may be of solidconstruction. It is, however, slotted at 38 in substantial registry withthe slots 30, though the slots 38 are of less overall length than theslots 30. A transverse slot 40 is also provided, but instead of joiningthe slots 38 at the ends thereof, it joins those slots at pointsintermediate their length, so as to form two overhanging tongues 42 and44. The plunger 36 is slidable within the bar 28, and a spring 46pressing against a closed end member 48 of the bar and a head 50 of theplunger urges the plunger 36 against the opposite end of the bar,substantially as shown in Figs. 8 and 9. In that spring urged position,the

tongue 42 of the plunger normally closes the transverse slot 32 of thebar. A thumb rod 52 is slidable through the end member 48 and is securedto the head 50 of the plunger so that the plunger may be withdrawn tothe extent indicated in Fig. 10 so as to bring the cross slots 32 and 49into substantial registry. A pin 54 is set into the back side of the bar28 and enters a slot 56in the plunger 36 to keep the plunger from willbe maintained in substantial alignment at all times.

With the handle thus constituted, it serves as a guide or retainer for abrace or stay by which the door may be held in part open position. Thestay and its fittings is preferably of the form illustrated in Figs. 1to '7, and 11 inclusive, where a rod or boom 69 has a universalconnection at one end with a mounting plate 62, while the other end ofthe boom has an angular extension or arm 6 adapted to extend over thegap 14 between the door and casing to a point well beyond the bar 48 ofthe handle where it ends in a head or enlargement 66. The mounting plate62 is of suchcharacter as to match in general appearance and dimensionswith the handle l8, and is adapted to be mounted in parallelismtherewith on the casing l2 and adjacent the gap l4, and when so mounted,the arm 64 of the boom may be moved to coincide with the notch 32 of thebar 28. v

The universal connection of the boom B0, is effected by reducing the endportion as at 68 and passing it through a cross bore in a block 10,after itis headed over at T2 sufficiently to hold the parts against freeturning, but loose enough to allow turning or rotating by hand. Theblock 10 is pivotally mounted between a pair of ears or lugs 14 carriedby the mounting plate 62, by meansof one way screws 16 passing throughthe ears and threaded into the ends of the block 10, substantially asshown in Fig. 6. That mounting of the boom 60 provides for rotation ofthe arm .64 from a position extending over the edge of the door as shownin Figs. 1 to 4, through substantially or so that the arm extends awayfrom the door, and the universal mounting also permits the boom as awhole to tilt outwardly from the casing, or lie close to andsubstantially parallel with the casing as shown in dotted and full linesin Fig. 5. The rotation to and from a position extending over the edgeof the door is for the purpose of coupling and uncoupling the boom withthe handle so as to serve either as a guard mechanism and door stay, orfor permitting full opening of the door when uncoupled.

Contributing to the device as a door stay, a friction device is providedthat operates to hold the boom in any position of inclination withrespect to the casing that the boom may be moved to, incident to openingor closing of the door when the coupling is made. A housing 80, in theform of a tube that may have a closed end 82, is secured in the casingl2 so as to be perpendicular to the bottom of the mounting plate 62, andis held in place when the mounting plate is secured by the usual screws20 driven into the casing. It is preferred that the near end of thehousing 80 be open and have a peripheral flange or lip 84 seating withina counter sink of the casing. Centrally of the face of the housing end,an aperture 86 is provided for passage and movement of a connector orrod 88, that for the most part is enclosed by the housing 88 and extendsthroughout the length thereof. The inner end of the rod 88 is reduced at99 to receive a bushing or the like in the form of a washer 92, that isheld in place by riveting as at 94. The bushing 92 is of such size as toslide within the housing 89, and tends to center the rod 88 therewith,and prevent binding. When the boom is in folded position as shown inFig. 5, the bushing will be at the end of the housing near the head 82.Unintentional movement of rod 88 within the housing is prevented bymeans of a spring sleeve or collett 98, that has a flange 98 received bya recess in the flange 84 of the housing, and disposed against the underside of the mounting plate 62, while the opposite end of the sleeve isslit to provide a pair or more of inwardly pressing spring tonguesliiil-frictionally engaging the rod 88. As the rod 88 is moved in andout of the housing 80, it slides within the spring sleeve, and firmlyholds the rod in the position desired.

An articulated connection is made between the rod 88 and the boom 68, bymeans of a sleeve IDZslidable and rotatable with respect to the boom 60,and that provides an apertured ear or lug I84, adapted to bereceived ina notch I06 of the adjacent end of the rod 88, where a hinged connectionis effected by a pin I08. With the boom 69 and rod 88 thus connected,anyoscillation or tilting of the boom with respect to the mounting plate82, or the casing on which it is mounted, will move the rod within thesleeve 96 and along the housing 88, and the positions of the boomselected will be maintained, until an intentional force alters itsposition. That will obtain even though the boom be coupled to the handleelement of a door.

Normally, the parts will be associated as illustrated in Fig. 1, withthe exception that the arm 64 of the boom will be extending to the leftas indicated in dashed lines, under which circumstances, the door willbe free for wide open movement, and unencumbered by the guard mechanism.When it is desired that the mechanism serve as a guard for the openingand stay for the door, the boom while maintained substantially fiatagainst the casing 12 is rotated so that the arm extends across the edgeof the door. That will dispose the arm 68 directly over the open end ofthe notch 32 in the bar of the handle, and if the thumb rod 52 is thenraised, the arm 62 may be passed into the juncture of the notches 39 and32. Release of the thumb rod 52 will allow the spring 46 to move theplunger 36 so that the tongue 42 passes over the arm 64 and closes thenotch 32. The relation of the parts so coupled is fully illustrated inFigs. 1 to 4, 8, 9 and 11. The relation of the parts while the arm 64 ispassing laterally into the slots is shown in Fig. 10. To make thatcoupling of the boom and handle, and in fact to uncouple them, the doormust be tightly closed, otherwise the arm 64 and transverse notches willnot align sufiiciently.

With the parts thus coupled, the door may be opened to any positionwithin the limits defined by the longitudinal movement of the rod 88within the housing 80. What ever part open position the door is movedto, the friction device will hold a ainst unintentional forces appliedto the door. Thus breezes or gusts of air will not slam the door closed,or jerk it further open against the limits of the mechanism. One suchpart open position is illustrated in' Fig; 4, where it will be notedthat the boom in tilting'outwardly from the casing has partiallywithdrawn the rod 88 from its housing, and through the friction de-'vice or sleeve. At the same time, the boom has rotated within theblock") so that the arm '64 is canted around to assume a relationpractically parallel with the face of the door It).

The position of the parts shown in Fig. 4 is but one of an infinitenumber that can be had within the mechanical limits of the device. In adevice constructed in accordance with the foregoing disclosure, wherethe boom 68 and rod 88 are each six inches long, and where the rod 88 iscapable of projecting out of the casing five inches, while the length ofslot 30 in the'bar is three inches, it is found that the door may beopened as much as five inches from the tight disposed. in and withdrawnfrom the cross slots 7 or notches 32 and 48 only when'the 'door is intightly closed position, thearm 64 cannot be withdrawn while the door isopen sufficient to permit a hand to be inserted.

When the guard mechanism is'so coupled, the door may be opened orclosed'to any extent within the limits provided by the device by a merepull or push upon the handle or door. When it is desired to uncouple theguard mechanism, the

door is moved to the closed position, if it is not' already so, then theplunger 38- is lifted to withdraw the tongue 42 from the notch 32, andthe arm 64 is rotated to the left out of the way. The tongues 42 and 44reinforce the walls of the bar 28, so that it will be practicallyimpossible for an unauthorized person to bend or warp the structureenough to uncouple, which might otherwise be possible by insertion of abar or other tool.

It is desirable to incorporate with the structure, a night latch orbolt, by which all opening movement of the door is'prevented, exceptwhen the latch is released. I accomplish that by fasho ioning one of thefeet 26 forythe handle' to provide a pair of loops or rings l 58, one oneach side of the foot, and within the bore of which there is a bolt H2fitted with a pin or finger piece I M J by which the bolt may be movedinto projected or withdrawn position. A lip or web H8 extends around thebolt llz and is sufficiently spaced from the rings Hi! to form aU-shaped slct H8, forming a guide and retainer for the pin 4 l4. Asshown in Figs. 1 and 2 the bolt I I2 is in the withdrawn position.Movement of the pin l M from the right hand side of the handle throughthe slot H8 to the other side of the handle projects the bolt H2 into ahole-J28 provided in the easing beneath the end of the mounting plate62.

' This is the position with the latch on, and the mounting plate 62reinforces the casing against breaking away when one tries to forcethe'door open.

The device is also adaptable to serve as a mere stay mechanism, in whichinstance it operates to hold the door or closure member with which it isassociated in any position of opening. An instance of the kind is thatoftransoms, and

other simple hinged or pivoted closures where wide or full opening ofthe member is desired. The parts of the mechanism are so proportioned.that installation in a manner that the friction device is on a linewith the hinge pivots of theclosure member, permits opening of themember with the stay mechanism attached to about 90", which will notinterfere with passage through the opening. Note a specific example. Therod housing 80 is set in the door or transom casing in line with thehinged edge of the door, and the boom is then mounted in the usualmanner, but with the pivot 10 of the boom located beyond the edge of thedoor, while the free end extends toward the free edge of the door, andthe arm 54 is adapted to extend over the door edge. The handle is isthen mounted on the adjacent edge of the door so that when the door istightly closed the arm 64 will be disposed in the end of the slots 3E!and 38 at their juncture with the cross notches 32 and 40 respectively.With the handle so mounted, but with the remaining portions of handleslots extending away from the door pivot, provision will be made fortravel of the arm 64 along the slots as the door is moved in opening orclosing. As the door is opened, the boom 63! will be inclined withrespect to its mounting support, which in turn will withdraw the rod 88from its housing 80, its movement being restrained by the frictionalengagement of the sleeve 96 which is suflicient to retain the door inany position of opening to which it may be moved within the limits ofthe mechanism. While the door is in the closed position, the staymechanism may be uncoupled or recoupled as has been elsewhere described,so that when desired, the benefits derived from the stay mechanism maybe either dispensed with or made use of.

It has been found that the overall length of the housing 80 and the rod88 may be six inches or more without encountering difficulties inmounting even in buildings of inferior construction, for the minimumthickness of the casings about the doors is usually more than the lengthof the housing 80, so that there is little or no danger of the housingextending clear through the door casing, when the fixture is properlymounted.

It is desirable that the boom 60 and the rod 88 be made of relativelyhard metal so that the purpose of the mechanism may not be defeated bybending, springing or cutting. To aid or simplify in packing, the lugI04 of the boom engaging sleeve is of sufficient length to extendthrough the aperture 86 of the mounting plate 62, and permit the rod 88that is pivoted thereto to fold flat against the under side of themounting plate 62, substantially .as shown in Fig. '7. That makes itpossible to pack the mechanism in a narrow flat carton, which will takebut little space upon the merchants shelves, and a device is thusprovided that is adapted by simple mounting procedure to act as either adoor opening guard, or as a mere door stay. Perfect installation isquickly and easily accomplished with but few and simple tools, ascrewdriver, brace and bit, with perhaps a gimlet is all that is needed.

Once installed, the device is proof against disorganizing forces fromthe outside, and sufiices to hold the door in adjusted position withoutrat tling. The keeper element for the boom, that is the handle 28,serves as a manual for manipulation of the door.

While I prefer that the keeper element, that is the member It, be in theform of a handle, it

may bedeprived of its hand engaging features, and be characterizedmerely as a slotted guide means with a closure for the open end of theslot and my nomenclature of a handle come prehends the inclusion of sucha simple element.
